28 indicates foot rest; for the operators feetatljuetahly secured to theIngright portion of the axles :2, and 29 e hand lever pivotally securedto draft beam 26.

The construction oi cultivator nhove described and illustrated in thedrawings is that of a machine now on the market, .manu- 'lacturcd hy theRock island Plow Company, Rock island, 111., and known as The DictatorCultivator.

i In order to acccnimodalc my iinprowal cottnn. chiiippcr attachment tohe herein "er described l. have changed the position of the braces forthe ttehapcd frame and in the drawings nhcw the changes in which 32 and33 indicate said braces connectin the. U shaped i'ran'ie G and crossliar tftlie hracesi 32 being angular as shown and provided with cleats34 spaced. apartto form guideways 35, and 36 indicates other cleats eecured to the diner sides ofU shapcd frame and spaced apart to form othergruideways 37in vertical alineini-int with guidcwaye 35.

3S indicative an inverted U-shaped frame elidahly mom i guideways 35 and37. 'llhe free e ct? "ffrrune 38 are secured to means of clips 48, saidf their edges extending toward upright bars 39 between which isjournaled the chopping roller 40. Roller 40 consists of a drum 41 havingrods 42 extending outwardly therefrom to which are secured the two rings43, spaced apart to form a slot 44, the rings 43 running one on eitherside of the row of plants.

45 indicates slides extending transversely of the guides being arrangedin pairs secured to rods 42 and roller, said and having each other. Thechopping devices consist of frames 46 and 47 slidably mounted on slides45 by *anics 4G and 4? having chopping blades 49 and 50 secured thereto.

51 indicates springs secured to each frame 46 or 47 and to the drum 41which normally hold the frames 46 and 47 so that the edges of choppingblades 49 and 50 over lap each other acting in the nature of a pair ofshears. Posts 52 are secured to the drum 4]. between each of the frames46 and 47 to engage said frames and limit the movement thereof under theimpulse of the springs 51 and to also insure centering of the blades 49and 50 between the rings 43. v

53 indicates a catch "ournaled on each frame 46 and having an angularupright portion 54 to engage the end of frame 47 and hold the two framesso that the blades 49 and 50 are separated and against the impulse ofsprings 51.

55 indicates an angular extension on the other end of catches 53 thatare engaged by the lower end of plate 56 slidably mounted on one of thebars 39.

53 indicates springs 53 normally in position to engage of frame 47 asstated.

When in its lowermost position the' plate 56 engages angular extension55 and swings the catch so that the end 54 is out of err gagement withthe end of frame 47 and the frames 46 and 47 are released to the actionof springs 51 which slide said frames on guides 45 so that the cuttingblades 49 and 50 are brought together and any plants that may be engagedthereby will be either cut off or pulled out of the ground.

57 indicates arms secured to the lower end of each bar 39, extendingbackwardly therefrom and slanting inwardly toward the chopping roller 40to engage rollers 58 journaled on arms 59 secured to frames 4-(3and 47.The function of the arms 57 engaging rollers 58 is to push frames 46 and47 baclr against the impulse of springs 51 so that the frames resume thepositions occupied before being released to the action of the springs asstated and the catch 53 engages the end of frame 47. The plate 56 hasvertical. slots 56 therein to receive pins 59 secured to bar 39.

(30 indicates a lever fulcrumcd on the side to hold the c'atchcs the endblades secured to said frames,

of U-shaped frame 38 and having one arm connected with plate 56 by meansof rod 61 so that the plate may be tor whenever the plant growth is sothin that no plants need be cut out.

When in a raised position the plate til does not engage the extension 55on catch 53 so that the frames 46 and 47 remain inactive and thechopping blades 49 and 50 do not operate.

(38 indicates a cross bar secured to the sides of frame 38 and (39indicates a bell crank lever fulcrumed on cross-bar 4 and having one ofits arms connected to cross-bar 68 by means of rod 70. This constructionadmitting of raising the frame 38 and chopping roller 40 when turningthe machine at the ends of rows and in going to and from the field.

Various changes in the proportions and construction of my device may beresorted to without departing from the scope of my invention and I donot therefore limit myself to the construction shown and described.
